Semifine section of the gland stained with toluidine blue and observed with the objective of 10x. We can distinguish the different parts of the gland: serous (dark blue-stained) and mucous acini (bluish red-stained), separated by fine collagen septa. We can also see the excretory conduits surrounded by connective tissue. Details of the excretory conduits (box in red) and acinar zones (boxes in blue and green) can be dobserved at higher magnification in other microphotographies
